In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!

Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

MCU VERSION: 01.04 r Version of MPU software : V1.04

BT Firmware: V00.46.R00.25 r Version of BT software : V0.46.R0.25.

VERSION UPGRADE METHOD

Save six sorts of file for Version Up (build.img, UPD_MPEG.VER, update.img, UPD_MCU.VER, UPD_BT.VER and NFOREBT.dfu) on an USB.
Turn the product power to be ON and insert the above mentioned USB.

MPEG software update
MCU software update
BT software update (Only a model with BT functional)
Reset, "do default setting" in the setting menu.
Check Version.

Insertion of USB will display the following Update screen.

Prepare files shown below according to the purpose for upgrading the software. (It is not necessary to prepare all files)

Item to upgrade	Use software
MPEG	build.img , UPD_MPEG.VER
MCU	update.img , UPD_MCU.VER
BT	NFOREBT.dfu , UPD_BT.VER

Upgrade the software in the order of MPEG, MCU, and BT. Be sure to perform Default Settings in the Setting after performing Version Up. If you do not perform the Version Up, the initialization of MPEG software will not be executed. In addition, the Main Body Reset SW located at the rear surface of Detach Panel is only for the Restart RESET of MCU and it does not mean to perform all of the initialization.
